Effect of abscisic acid and auxin on ribonuclease during ageing of bean endocarp tissue sections

The activity of RNase increases rapidly upon cutting sections of bean (Phascolus vulgaris L. var. Kentucky Wonder) endocarp, peaks within 4 to 8 hr and then declines. This rapid development of RNase activity is inhibited by cycloheximide. Auxin (αnaphthaleneacetic acid, NAA) accelerates the rate of...

Description
Summary:The activity of RNase increases rapidly upon cutting sections of bean (Phascolus vulgaris L. var. Kentucky Wonder) endocarp, peaks within 4 to 8 hr and then declines. This rapid development of RNase activity is inhibited by cycloheximide. Auxin (αnaphthaleneacetic acid, NAA) accelerates the rate of decline of RNase. Abscisic acid (ABA) enhances the level of RNase between 4 and 24 hr, associated with a decline in RNA, and this effect of ABA is obscured in the presence of auxin.
